Uncaught TypeError: useTracker is not a function! #322

Closed yaser-alazm closed 2 years ago

Hello.

It's my first time trying to work around with Meteor, so I have this project already created, I cloned the repo to my local and started to play around with it.

But I'm stuck with this error (Uncaught TypeError: useTracker is not a function!) every time trying to fetch data.

In the main.js on the server I'm trying to connect to the database and add some data:


import { Meteor } from "meteor/meteor";
import { Tasks } from "/imports/api/tasks";
import { Random } from "meteor/random";

const testData = [
  {
    title: Task1",
    hasDescription: true,
    commentsCount: 2,
    color: "#4e42c3",
    status: "incomplete"
  },
  {
    title:"Task2",
    customFields: [
      {
        _id: Random.id(),
        value: "Highest"
      }
    ],
    status: "incomplete"
  }
];

Meteor.startup(() => {
  // If the Tasks collection is empty, add some data.
  if (Tasks.find().count() === 0) {
    testData.forEach(task => Tasks.insert(task));
  }
});

in the Tasks.js file there is the creation on tasks collection and it's schema :


import { Mongo } from 'meteor/mongo';
import SimpleSchema from 'simpl-schema';

export const Tasks = new Mongo.Collection('tasks');

const regExId = SimpleSchema.RegEx.Id;

const { Integer } = SimpleSchema;

Tasks.schema = new SimpleSchema(
  {
    _id: {
      type: String,
      regEx: regExId
    },
    createdAt: {
      type: Date,
      autoValue() {
        if (this.isInsert) {
          return new Date();
        }
      }
    },
    updatedAt: {
      type: Date,
      autoValue() {
        if (this.isUpdate) {
          return new Date();
        }
      }
    },
    isPrivate: {
      type: Boolean,
      defaultValue: false
    },
    title: {
      type: String,
      min: 1,
      max: 500
    },
    totalTimeTracked: {
      type: Integer,
      defaultValue: 0,
      min: 0
    },
    commentsCount: {
      type: Integer,
      defaultValue: 0,
      min: 0
    },
    filesCount: {
      type: Integer,
      defaultValue: 0,
      min: 0
    },
    hasDescription: {
      type: Boolean,
      defaultValue: false
    },
    dueDate: Date,
    repeat: {
      type: Object,
      defaultValue: {}
    },
    'repeat.interval': {
      type: Integer,
      min: 0,
      max: 365
    },
    completedAt: {
      type: Date
    },
    status: {
      type: String,
      allowedValues: ['incomplete', 'completed']
    },
    customFields: {
      type: Array,
      defaultValue: []
    },
    'customFields.$': {
      type: Object
    },
    'customFields.$._id': {
      type: String,
      regEx: regExId
    },
    'customFields.$.value': {
      type: SimpleSchema.oneOf(String, Number, Date)
    },
    color: {
      type: String,
      regEx: /^#[0-9A-F]{6}$/i
    }
  },
  {
    clean: {
      filter: true,
      autoConvert: true,
      removeEmptyStrings: false,
      trimStrings: false,
      getAutoValues: true,
      removeNullsFromArrays: true
    },
    requiredByDefault: false
  }
);

Tasks.attachSchema(Tasks.schema);

In the ui/app.js I just try to use useTracker to fetch the data, in the app.js : 


import React from 'react';

import { useTracker } from 'meteor/react-meteor-data';

import { Tasks } from '../api/tasks/';

const App = () => {
  const tasks = useTracker(() => {
    Tasks.find({}).fetch();
  }, []);
  // console.log(tasks);
  return (
    <>
      <h1>Test</h1>
    </>
  );
};

export default App;

this is the .meteor/packages file content

Any recommendations ?

CaptainN commented 3 years ago

It looks like configuration is fine, import statement is fine - not sure what's going on there. You do have an error in your useTracker block, but that would cause a different problem:

const tasks = useTracker(() => {
    Tasks.find({}).fetch();
}, []);

You need to return that value:

const tasks = useTracker(() => {
    return Tasks.find({}).fetch();
}, []);
yaser-alazm commented 3 years ago

@CaptainN I already consider this to cause this issue, but still no luck! I think it's something to deal with the packages version.

Maybe try meteor reset - it's definitely a strange error...

yaser-alazm commented 3 years ago

meteor reset

No luck unfortunately!

yaser-alazm commented 3 years ago

@benjamn @grigio @glasser can you check this out please ?

glasser commented 3 years ago

Sorry, I don't work on Meteor these days!

CaptainN commented 3 years ago

Maybe ask in the Meteor Forums. I don't know what's going on here.

filipenevola commented 3 years ago

Hi @yaser-alazem, could you provide a reproduction? 😉

Read more here

We have many projects using react-meteor-data so it must be something different in your project.

Maybe you are using an old version of Meteor with an old version of react-meteor-data? useTracker is only available in newer versions.

filipenevola commented 2 years ago

I'm closing this issue because we haven't heard anything from the original poster for a while.
